A woman who has the blood type AB and is homozygous dominant for Rh marries a man who has Type A+ blood, but his mother was Type O - blood.

3) What is the probability of the parents' having a child with Type O blood.

Mother: Genotype:- AB

             Phenotype:- AB+

Father/Man : Genotype:- AA or AO

                      Phenotype:- A+

Probability of the parents' having a child with Type O blood. 

    = 0.25 or 25%

What are the possible offspring genotypes and phenotypes? Since the father has two possible genotypes, I'm confused... sorry.

Just a minute please.

Actually the father's genotype is AO only because his mother had blood group O-

So Possible Genotypes of the offspring would be:

AA - 25%

AO - 25%

AB - 25%

BO - 25%

Phenotypes would be

A

B

AB

O
